Simple question:
Should I turn CPU hyperthreading on or off on a dedicated cruncher?

I was about to ask a similar question. I'll leave hyperthreading on having read this.
I think this is fool-proof but could you just try it for me please? • There are 10 types of people in the world; those who understand binary, and those who don’t

When I get a moment, I plan to experiment with this as I rather doubt that the improvement is as high as 50% - I am thinking maybe 20-25% but I need to try it for myself

On most projects you will get about 30% improvement with HT on. The projects that run really tight code (PG and SRBase) you are better to turn HT off.
